AIR COMPRESSOR AND. THE LIKE.

Applicationfilcd November 17, 1927. Serial No. 233,866.

My invention relates to apparatus employing cylinders having reciprocating pistons therein and is of particular use in connection with air compressors.

The invention has for its object the provision. of improved means for cooling such apparatus by means of air suitably blasted upon the cylinders. I employ a blast fan at the outer end of a cylinder of such a machine and having its axis of rotation substantially at right angles to the axis of the cylinder. I also employ a funnel extending along the fan axis, the fan being at the mouth of the funnel, the spout of the funnel being cut away at one side ofthe funnel, the outer end of the cylinder being located at the spout where the spout is laterally cut away.

In the preferred embodiment of the 1nvention,themouth of the funnel is also laterally cut away to form a continuation of the lateral opening in the spout, the lateral opening in the funnel mouth permitt ng the fan to blast air upon apart of the cylinder without the intermediation of the funnel spout. The spout of the funnel also desirably has an end wall opposite the funnel mouth and constituting-a bafile for deflecting a r upon the cylinder. An air compressonor other similar apparatus thus blasted. WItl1 aII' 1S effectively and enduringly cooled during its operation.

The invention willbe more fully explained by reference to the accompanying drawing in which Fig. 1 is a View of one form of'compressor. in elevation with the air cooling means of my invention shown partially n section and partially in elevation; Fig. 2 1s a perspective view of the preferred form of tunnel; Fig. 3 is a sectional view on l1ne 3 3 of Fig. 1; and Fig. l is a sectional View on line lt- 130f; Fig. 1.

The air compressor illustratedincludes a pair of cylinders 1 containing pistons 2 that reciprocate therein, th ese plstons being con-v nected by means of cranks 3 to the crank shaft l. The cranks and crank shaft are disposed within a crank case 5 which is provided upon a suitable base block6, A fly wheel 7 is upon one end of the shaft l and a pulleyS isupontheother, end of SllClShflflZ. Thefan belt 9 is drivenby the pulley 8 and drives the pulley 10 which is provided upon the hub 11 of the fan 12. This hub turns upon a shaft 13 which is suitably secured upon the upper or outer ends of the cylinders 1, the common axis of the fan t1I1Cl" tlllS shaft being substantially at right angles to the axes of the two cylinders.

The usual'or suitable air pipes 14 and 15 the axis ofthe funnel being'preferably substantially coaxial with'the fan. The fan, is at and preferably within the mouth of the funnel and the spout and funnel mouth. are desirably both cut away at one side of the funnel, as respectively indicated at 17' and 16, the end of the cylinder entering the funnel spout laterally where the spout is lateral: ly cut away, at 17. The braces 18 and'19 that are'secured tothe compressor and the funnel, as illustrated most clearly in Fig. 4', support the funnel'upon the compressor. The funnel spout hasan'end Wall 20 at one side of the cylinder and opposite the funnel mouth, this end wall constituting a baffle for deflecting air upon the cylinder.

It will be apparent that the air whichis blasted toward the compressor by the fan is directedin ample volume upon andalong the cylinders, the air being partially directedin its flow by the funnel spout and'the end wall 20 ofthe spout and elsewhere having direct access to the compressor from the fan and through the lateral opening 16 in the mouth of the funnel.

Changes may be made without departing from the invention. I

Having thus described my invention, I claim:
